Has Your Gastric Sleeve Stopped Working?
If the weight has crept back or you never reached your goal, you're not alone. Over time the stomach can stretch, hormones shift, and old habits return. A gastric sleeve revision helps tighten or reshape your sleeve so you feel full sooner, ease reflux, and get back on track.
Dr. El Djouzi has performed hundreds of revisions and knows how to pinpoint why a first surgery fell short. Answer a few quick questions and we'll tell you whether a revision makes sense for you.
